On your order confirmation email tap change tickets and follow the steps. You'll receive an invoice via email to pay the balance ($2 extra per ticket on the weekend). Once that is paid you'll receive an email with a link to your new tickets. Please note if you change from a weekend to a weekday, you will not be given a refund for the difference.
